Galaxy Anatomy: Instructions for the General Public

Do you believe you live in some state of darkness, full of worry and uncertainty? Do you want to make a change of your life? Scientific progress may help you. The simplest way to achieve this change is for you to forget the misery that comes from the miniature world of your immediate life, zoom out of this world, look at the large natural structure of the universe, and find its meaning. As you know, the large scale structure is not relevant to humans ’ activity. Unfortunately, the meaning has not been identified. Now, with Dr. He’s study on galaxies, the meaning of the universe may emerge. The good news is that people, whatever their origin (politician, lawyer, doctor, musician, or beggar), could claim a big discovery on the meaning by playing a computer software of galaxy anatomy. This article is a simple instruction for the design of such a program. 1. What is a galaxy image? Everyone needs attention from others. Businessmen know this fact, and they developed the commercial digital cameras. Now, we pay attention to galaxies and take their images with telescopes. Spiral galaxies are flat, and a digital image of a face-on spiral galaxy is three arrays of numbers. Each array corresponds to a density distribution of one color (e.g., red). However, we study the stellar distribution of galaxies, and their images are taken with longer wavelengt
